Scientific paper

This thesis focuses on the properties of exoplanet atmospheres. The results for ground-based near-infrared secondary eclipse observations of three different exoplanets, TrES-3b, HAT-P-1b and WASP-33b, are presented which have been obtained with ground-based telescopes as part of the GROUSE project. In addition to secondary eclipse observations, the broadband transmission spectrum of the super-Earth GJ1214b is also presented. The transmission spectrum for this low-density planet indicates that it probably has a low-metallicity, hydrogen dominated atmosphere. Finally the results for an ensemble study of the thermal emission properties of hot Jupiters is presented, including the average spectrum for these planets separated based on the level of incident radiation and the activity of their host-stars.
